It allows a paintable surface finish to be obtained by vacuum-bag moulding processes. It can be used directly against a suitably release treated mould surface, with prepreg or SPRINT™ plies laid up behind it. When fully cured with SPRINT™ or prepreg, SF 75-90 forms a stable sand-able surface which, once lightly sanded to provide a key for painting, reduces print-through of the underlying laminate. The epoxy system is supplied ready impregnated into a supporting medium and ready catalysed, requiring only a low to moderate temperature cure. |
